How to Use an Inhaler Correctly: A Step-by-Step Guide for Patients

Using an inhaler the right way is essential for managing asthma, COPD, and other respiratory conditions. Incorrect inhaler technique can lead to poor symptom control and unnecessary flare-ups. This guide walks you through the correct steps for using your inhaler and offers tips to maximize its effectiveness.

Why Proper Inhaler Technique Matters

Many patients unknowingly use their inhalers incorrectly, which can lead to:

• Poor medication delivery to the lungs
• Increased risk of asthma or COPD attacks
• Wasted medication
• Delayed symptom relief

Learning and practicing the correct technique ensures that your lungs receive the full benefit of the medication.

Types of Inhalers

There are two main types of inhalers:

1. Metered-Dose Inhaler (MDI)

Also known as a pressurized inhaler, this type delivers a specific dose of medication in aerosol form.

2. Dry Powder Inhaler (DPI)

This device delivers medication in a dry powder form and requires a strong, fast inhalation.

Tip: Always check your specific inhaler's instructions or ask your doctor or pharmacist to demonstrate.
